Urukuta Microphone Stethoscope yo Gupfukirana Kwumva Binyuze mu rukuta
Imikoreshereze y'ibicuruzwa
Ibisobanuro
Izi transducers ebyiri zumviriza ukoresheje igikoresho cyurukuta nicyo kigezweho cyane mubicuruzwa bisa muri iki gihe, bishobora guha abumva amakuru y amajwi asobanutse bagiye kumenya.Iyi ni amplifier idasanzwe izatora urusaku ruto binyuze mubintu bikomeye nkurukuta, kuburyo ushobora kumva ibibera kurundi ruhande.Guhuza mikoro ni ceramic pin yakozwe muburyo bwihariye bwo guhindura ibinyeganyega mu rusaku rwumvikana.Ifite transducers ebyiri zikomeye hamwe zigizwe nigikoresho kidasanzwe cyo kugenzura kugirango abapolisi, gereza nibindi.

Intangiriro y'Ikigo
Mu mwaka wa 2008, Beijing Hewei Yongtai Technology Co., LTD yashinzwe i Beijing. Twibande ku iterambere n’imikorere y’ibikoresho by’umutekano bidasanzwe, cyane cyane bikurikiza amategeko y’umutekano rusange, abapolisi bitwaje intwaro, igisirikare, gasutamo n’izindi nzego z’umutekano z’igihugu.
Mu mwaka wa 2010, muri Guannan hashyizweho ibikoresho bya polisi bya Jiangsu Hewei, LTD.
Muri 2015, i Shenzhen hashyizweho ikigo cya gisirikare-gipolisi cya Reserch n’iterambere. Hibandwa ku guteza imbere ibikoresho by’umutekano bidasanzwe, byateje imbere amoko arenga 200 y’ibikoresho by’umutekano by’umwuga.
Imurikagurisha ryo mu mahanga
Beijing Heweiyongtai Sci & Tech Co., Ltd. ni Isoko Ryambere ritanga EOD n'umutekano wibisubizo.Abakozi bacu bose ni abahanga mubuhanga mubuhanga nubuyobozi kugirango baguhe serivisi zuzuye.
Ibicuruzwa byose bifite raporo yikizamini cyurwego rwumwuga hamwe nimpamyabushobozi, nyamuneka humura gutumiza ibicuruzwa byacu.
Igenzura rikomeye kugirango wizere ibicuruzwa birebire ubuzima hamwe nu mukoresha akora neza.
Hamwe nuburambe burenze imyaka 10 yinganda kuri EOD, ibikoresho byo kurwanya iterabwoba, ibikoresho byubwenge, nibindi.
Twakoresheje ubuhanga abakiriya barenga 60 kwisi yose.
Nta MOQ kubintu byinshi, gutanga byihuse kubintu byabigenewe.
